MEAP ch1 v12, Section 1.5.1 about graina2 HOT 8 CLOSED

This is a breaking change with Grails 2.3. The list action no longer exists in the scaffolding. We will need to update the chapter and source code to use the index action instead.

Thank you, Peter. With your help above, and looking at the official "Scaffolding - Reference Documentation" at http://grails.org/doc/latest/guide/scaffolding.html (currently for the version 2.3.1), I think it works now.

I commented out the entire index method in the QuoteController.groovy class as follows, and it seems to work now (meaning, I am able to see the quote list which I was not able to see before).

//def index() { 
//redirect(action: "home")
//}

Thank you again for the quick feedback, it was very helpful (especially for a newbie like myself).

Glad it's working for you. I'd like to keep this open as a reminder that we need to update the QOTD app.

from graina2.

I see the index page, but I cannot see the list Larry, Chuck and Eric's quotes.

I inserted three record using "grails console", and it prints 3 when I command "print qotd.Quote.count()"

Interestingly I don't see the 3 results in scaffolding index(list) page.

What's wrong with my index page?

Grails 2.3.4

Have you switched to a persistent database? If not, any changes you make via the console UI will not have an effect on the running application.

from graina2.

Thank you for your response.

I changed my environment settings for development as follwos:

development {
    dataSource {
        dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
        url = "jdbc:h2:file:~/devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
    }
}

I believe that it's enough to use persistent database.

I see the results "grails console". I can retreive results using random() action method described in your book.

I cannot see the three records only when I access the index() page supported by "scaffolding".

It's quite weired.

I tried to import your qotd application provided in github. It doesn't seem to work with Grails 2.3.4.

Can I know which version I have to choose on the fly?

from graina2.

Hmm...

I found an answer here: http://www.grailsexample.net/instant-ui-dynamic-scaffolding/#comment-29334

However, it sees like a bug of Grails 2.3.4 because I have to pass the List even using "dynamic" scaffolding like:

def index() {
    [quoteInstanceList : Quote.list()]
}

I believe that some contents must be changed if your book's supposed to support the latest version of Grails.

Thank you.

The sample source code is now based on Grails 2.3.4. @nasiajai please check your code against that. You should not be overriding the index action in your controller.
